Decoupling retrieval quality from generative reasoning: A multi-dimensional benchmark of RAG architectures [PDF]

EPJ Web of Conferences
Traditional search engine returns ranked lists for humans to interpret. Retrieval Augmented Generation pipelines go further, feeding retrieved context directly into large language models to synthesize knowledge rather than simply surface it.
